In the News/Activism forum, on a thread titled Technology draws bead on hydraulic fracturing, thackney wrote responding to this
Didnt know T Rexes were found several thousands of feet down but oil has. Some oil make come from fossil decomposition but not todays oil. We still dont know the processes involved. But there is a hint, where radon gas is pleantiful we also find natural gas and oil.
“I’ll go back to the first question again. A Sedimentary Basin can be tens of thousands of feet deep. It is material laid down from the surface involving lakes or oceans. The world didn’t always look like it did today. Depositing a couple of centimeters of sediment every thousand of years adds up to quite a bit over a few hundred million years.”
Yea and Antartica was once in the tropics, Everest was once below or at sea level and present day Chicago is built upon sea shells. What your offering is an interesting but unproven assertion and does not explain oil and natural gas “plays” found all over the place. Nor is that view generally accepted but may explain some oil and natural gas fields but not all.
Name a single oil field not in a sedimentary basin. Just name one.
Name a single oil field found in Igneous Rock and not sourced to Sedimentary Sources.
